Startup Idea: Ecommerce Multi-site Product Listing Sync Tool

Startup idea to develop a comprehensive software tool to simplify and synchronize product listing across multiple ecommerce sites, potentially eliminating the manual task of copying/pasting identical information on different sites.

I work in ecommerce and in our company, we list products on various sites (about four per contract). However, it can be tedious to copy/paste the same information on multiple sites. I have looked into some software that will allow you to sync a few sites together and upload your product information simultaneously. However, they are very limited and they do not always include the best options. For instance, we can upload via bigcommerce and amazon but ebay would not be included.
